Physical properties should you consider in choosing materials for building a flotation device in times of flooding are:

  • Wood should be used since it floats on water due to its lower density. Depending on its density, an object will either float or sink in another substance.
  • An object will float if its density is lower than the liquid it is placed in.
  • An object will sink if its weight is greater than the liquid it is submerged in.
  • To trap air for floating, a thin, inflatable device like a rubber raft is the best option.
  • A personal flotation device you select meets the following criteria: It is the right size and has adequate buoyancy to sustain you in the water; It is the suitable type for your boating location and activity.
  • It received approval from the United States Coast Guard.
